Microsoft celebrates as Office 365 hits 1 million users in 100 days

Just over three months after its release, Microsoft is celebrating a million sales of Office 365 Home Premium. Going a long way to prove detractors of software subscriptions wrong, Microsoft's latest version of its office suite has managed to maintain average sales of more than one unit per second.

With a subscription costing $99.99 per year, Microsoft has clearly pocketed a healthy profit with this release, but the fact that the software can be installed on up to five machines may actually mean that sales figures are perhaps not as high as they could have been.

The sales figures were revealed through the Office blog where Microsoft compares the speed of sales to other popular services. The infographic shows that while Office 365 Home Premium took 3.5 months to obtain a million users, Spotify took 5 months and Instagram just 2.5 months.
